Definitions
- the subject of the invention is polyphenolic flavonoid derivative compositions for preventing and controlling most pathologies and the aging of tissues and living organisms. It also relates to a process for preparing these compositions and their applications, in particular in the cosmetic, dietary and therapeutic fields.
- ROS Reactive oxygen species
- the Maillard reactions that occur at the same time increase the reducing capacity of sugars and their derivatives.
- the dicarbonyl compounds that form acquire a much stronger oxidability than their precursors and easily transfer their electrons to oxygen, for example. From the initially formed superoxide anion, the same sequence of EOR as in the case of intracellular stress is produced. Thus, the carbonyl stress is doubled of a second type of oxidative stress.
- this new oxidative stress occurs outside the cells, within the extracellular matrix. It therefore relates to the amino acids or the residues of the proteins of this matrix, and in particular, the collagen and elastin fibers.
- This oxidative stress which is particularly important because the enzymatic protection systems are not as effective as those located in the cell, leads to an increase in the alkylation phenomena which add to the glycation and glycoxidation products resulting from the stress. carbonyl.
- carbonyl stress coupled with extracellular oxidative stress, is at least as important as intracellular oxidative stress in the development of aging and the establishment of tissue alterations accompanying the main pathologies.
- the study by the inventors of the phenomena leading to the aging of the tissues thus led them to a more extensive consideration of the biochemical mechanisms that are responsible for them and to come up with new concepts making it possible to define new biological targets of complementary actions for them. fight more effectively.
- the invention also aims to provide a method for obtaining such polyphenol derivatives from polyphenols of plant extracts.
- the invention aims to take advantage of the properties of these flavonoid polyphenolic compositions in cosmetology, dietetics and therapeutics.
- polyphenol derivative compositions of the invention are characterized in that said polyphenols contain monomers, oligomers or polymers of units corresponding to formula (I):
- These units are characterized by the simultaneous presence of a phloroglucinol type nucleus (core A) and a catechol type nucleus (core B), linked together by a 3-carbon bond such as C.
- core A phloroglucinol type nucleus
- core B catechol type nucleus
- ring A is joined to an additional oxygenated heterocycle by formation of a bond of one of its oxygens with carbon B of segment C (case of the flavonoid skeleton) of formula (II )
- segment C can be sp2 hybrids (double bond between b and c and carbonyl in a), as is the case with quercetin of formula (III),
- (IV) or its carbon a. can be sp3 hybrid alone, or finally be all 3 sp3 hybrids, as in the case of catechin of formula (V).
- Segment C most often serves as a point of attachment with the nuclei A of the other units to form the oligomers or polymers.
- Said derivatives are overactivated, with regard to their nucleophilic power, by alkylation of at least one phenolic function of each unit and stabilized by esterification with mixtures of fatty acids, mainly unsaturated (AGI), of all the others remaining free.
- AGI unsaturated
- the specific substitutions of the derivatives of the compositions of the invention lead to a modulation of their activity and render them capable of simultaneously and specifically inhibiting the main mechanisms involved in the major pathologies and aging mentioned above.
- the number of -O-alkyl groups per molecule does not equal the number of hydroxyls present on average per unit and, preferably, it is 1 or 2, more especially equal to 1.
- the alkyl group (s) are more particularly methyl, isopropyl or tert-butyl groups.
- the effective stabilization is obtained by formation of AG esters between the hydroxyl functions (alcoholic and phenolic), remaining free after alkylation (from 2 to 3, preferably 3), and fatty acids derived from vegetable oils characterized by their particular richness in predominantly unsaturated fatty acids (AGI).
- the oils are chosen for their favorable impact on health.
- the assets obtained then contain proportions of unsaturated fatty acids identical to those of the oils from which they come.
- Said esters preferably comprise mixtures of acyl radicals R of the fatty acids of olive oil (Olea europea) or of grape seed oil (Vitis vinifera).
- PUFA 15-18%): diunsaturated (linoleic) and triunsaturated (linolenic) of the C 6 -6 and C 3 -3 series, present in the derivatives of the invention in proportions identical to those of the oils which exert maximum health benefit, according to data from epidemiology.
- This stabilization also makes it possible to protect the overactivated flavonoid polyphenols from destruction. certain premature (oxidation in air or light), while giving them a lipophilic character in order to increase their chances of being resorbed and to act.
- this stabilization is, however, temporary, and is no longer effective when the derivatives are placed in a situation to act, in order to restore all their antioxidant power. It must therefore be reversible by simple action of the biological systems to which the stabilizing groups are then exposed, and in particular, enzymes such as lipases, esterases or proteases.

- an alkylating agent in particular an anhydride or an acid chloride
- the alkylation reaction uses commercially available reagents, such as halides (idodides, bromides, ...), or sulfuric esters with one and a half chemical equivalent). They are added slowly to a solution of the polyphenol extract in an aprotic solvent (anhydrous acetone, for example), and in the presence of a mineral base (potassium carbonate, etc.), brought to reflux, with stirring and atmosphere. inert (nitrogen, argon, ideally).
- an aprotic solvent anhydrous acetone, for example
- a mineral base potassium carbonate, etc.
- the alkylation reaction is stopped, after cooling, by adding a dilute acid (hydrochloric acid, for example) until an acidic pH is obtained.
- a dilute acid hydroochloric acid, for example
- the agitation is continued for an additional 45 min, approx.
- the reaction medium is concentrated under vacuum (evaporation of the solvent).
- the aqueous phase is extracted with an equal volume of immiscible solvent (such as ethyl acetate, dichloromethane, etc.), which is itself washed with two equivalent volumes of distilled water.
- the acylating agent is prepared from a vegetable oil by a process comprising: saponification of glycerides from a vegetable oil, followed by acidification, dehydration activation in the case where the acylating agent is an acid anhydride, or by chlorination, in the case where it is an acid chloride, but other derivatives conferring the same activation effect can be used (transesterification, enzymatic acylation, according to case).
- the saponification reaction is carried out in the aqueous phase in the presence of an alkaline agent such as potassium hydroxide in an amount at least stoichiometric, preferably at reflux temperature.
- an alkaline agent such as potassium hydroxide in an amount at least stoichiometric, preferably at reflux temperature.

- toluene is used and the water is trapped by a "Dean Stark" type system.
- the chlorination reaction is conducted in the presence of a solvent capable of dissolving the free fatty acids. It is catalyzed by a Lewis base and carried out by slow addition of the chlorinating agent, at a controlled temperature, close to 0 ° C. When the addition is complete, the stirring is prolonged at ambient temperature, then the medium The reaction is concentrated by evaporation in vacuo, and the chlorides are purified by distillation.

- a basic catalysis agent for example, triethylamine or pyridine
- acylating agents Four equivalents of anhydrides or AG chlorides as prepared above are used as acylating agents. They are added dropwise in solution in the reaction solvent, if it is not pyridine alone. In the case where the pyridine is both the solvent and the basic catalyst, a "reverse” addition is carried out. It is the solution of the polyphenol derivatives which is added dropwise to the preformed acylpyridiniums.
- An alternative that can be applied consists in adding, with vigorous stirring, a basic aqueous phase (Na 3 PO 4 , K 3 PO 4 ) to the organic solution (CHCl 3 , CH 2 Cl 2 ) of the alkylated polyphenol derivatives and acylation agents, thereby producing the conditions of Schotten-Baumann.
